SOS!!!高二英语～谢谢各位啦
1。你可能漏掉了某些单词。我推测这句的大概意思是：适当的户外运动、好的有规律的饮食习惯和避免过晚进食都有助于深睡眠。
are 之前的应该是主语成分。
2。 B It is + 时间段+since+ 一般过去时的句子 =
时间段+has passed+since+ 一般过去时的句子
It is seven years since he left here。 =
Seven years has passed since he left here。=
He has been away from here for seven years。=
He has been away from here...全部

He has been away from here since seven years ago。
3。 C 此题考察定语从句，the one 此时是先行词，此句省略了引导词that。
你将此句换为陈述句语序就可发现
This factory is the one that he once visited 。
此句主语是this factory 而非this。
。收起
